18 feet x 20 feet = 360 square feet. There are 9 square feet in one square yard, so 360 square feet = 40 square yards, not 12 square yards.
88 yrds
6x2-18x+12 = (6x-6)(x-2)
12 yards = 432 inches
It would cost $165 to carpet the entire room. you see 7 times 15 equals $105 and 5 times 12 equals $60. add $105 and $60 and you get $165. [: I would have to say that the answer above is wrong. 15 ft x 12 ft = 180 180 divided by 9 = 20 20 x 22$ = $440 Or you can convert the feet into yards first: 15 ft / 3 = 5 yds 12 ft / 3 = 4 yrds 5 yrds x 4 yrds = 20 yrds 20 yrds x 22$ = $440
x2 - 18x + 72 = 0 (x - 6)(x - 12) = 0 x ∈ {6, 12}
18x + 12y = 72 to get x-int. put y=0 18x + (12)(0) = 72 18x = 72 x = 4 your x-intercept is 4. this is the place where the line goes through the x-axis.
36 ÷ 3 = 12 yards There are 3 feet in a yard.
6(x - 2)(x - 1)
An equation to figure out what the answer of "x" is. eg, Removing the brackets - 6(3x-2) = 2(8x+4) 18x-12 = 16x + 8 18x-16x = 8+12 2x = 20 x = 10
3x**4+18x 3x(x**3+6)
-5 + 12x = 18x + 7Subtract 7 from each side:-12 + 12x = 18xSubtract 12x from each side:-12 = 6xDivide each side by 6:-2 = x
One mile is equal to 1760 yards - which is equal to 1760 x 3 = 5280 feet or 5280 x 12 = 63360 inches.
